 * Some forests were inventoried over a 2 to 3 year period; the survey date listed has been selected as the representative inventory year.

 

** Field location (also referred to as sample site or plot) on forest land: A timberland field location usually consisted of 5 to 7 sample points distributed on the sample acre; at each sample point a variable-radius main plot, 40 Basal Area Factor tally, and a seedling/sapling subplot were established. A woodland field location consisted of one fixed-radius main plot (1/10- or 1/20-acre) divided into 4 quadrants, located on the sample acre; within each quadrant, a seedling/sapling subplot was established.

 

***   “Other” includes sample sites classified as inaccessible or sample missed.
